IM PROVEMENT IN LAP-RINGS.

Our improved compound lap-ring is formed of two parts, each of which hasan opening at one side. The parts are secured together by rivets workingin slots, so that one part may be slid or adjusted on the other. Whenthey are adjusted in one position the openings in the respective partscoincide; but when adjusted in another position the openings do notcoincide, and hence the ring is closed, or becomes entire. Thisadjustment adapts the ring to be readily attached to or detached fromchain-links, single-tree or double-tree hooks, 8w.

Figures 1 and 2 are plan views of the respective inner and outer sidesof one of the parts of the compound lap-ring. Fig. 3 represents edge andside views of the ring closed, and Fig. 4 like views of the ring open.

The respective parts A and B, composing the compound ring, have a likeshape or general configuration and a similar cross-sectionto wit, asegment of a solid cylinder. A portion or section of the ring A is cutout near one end, and the ring B near the center, so that when the tworings are placed with their flat sides together and made to coincidethroughout, their ends lap past each other. They are secured by studs aa, which work in slots 1) b, the rivets being set in the ring A, theother near the ends, and the slots formed in the ring B at correspondingpoints.

By this construction and arrangement of parts, when the rings are slidon each other in one direction their respective openings coincide, as atc, Fig. 4, and the compound ring may then be connected with a chain-linkor single-tree or Whiffletree book. To close the ring, the respectiveparts A B are slid back till they coincide, as represented in Fig. 3,when the ends will lap past without touching, and close the opening, asat d.

What we claim is The combination of the ring A, open near one end, andhaving headed studs a a, with the ring B, open near the center, andprovided with slots corresponding in position with the said studs,substantially as and for the purpose specified.
